TO ALL'WHOM IT MAYCONCERN:

Be it known that I, JOSEPH CURRIER, of Portland, in the county of Cumberland, and State of Maine, have invented a. new and useful Improved Blind-Catch; and I .hereby declare thefollowing to be a full, clear, and exact description thereof, which will enable others to make, and use my invention, reference being had to the accompanying drawings,'form i ng part of this specification, in which- Figure 1 represents a. portion ofthe bottom edge of a blind, with my invention in position thereon.

Figure 2 shows a vertical longitudinal section of the same.

The object of my invention is to produce an easily and securely-operating blind-catch, and one `that presents an increased durability.

My inventionl consists in the attachment, to a blind-l )ottom,oi` a movable plate or bar, which has ltwo'studs' working into holes in the blind, so that the pla-te may be raised when the blind is to be unfastened, and the plate rests close against the bottom of the blind when it is fastened. Around one of the studs, and within the blind, in a hole therein made, is a spiral spring to secure the operation ofthe bar. p The other stud gives steadiess to the bar.

I have called the movable piece of metal a bar or plate, but it may be more clearly understood by reference to a b in the drawings-a showing the said bar, and b the catch or hook at either end.k The two studs are shown at 1 2. 2A has the spiral, c, fastened to the lower or inner end of the stud. d is a plate, secured to the bottom edge of the blind, as common', (see hl) c is a lever, attached at -the screw m, and passing aroundvthe stud'2, under the plate a, by a. slot in the end vof the lever, shown by dotted lines in fig. 1. By pressing upon the-end, 4, of the'lever, the catch will be thrown off the hook or staple, and the blind allowed to swing. A catchsneh as shown at 25, is on both ends of the plate a. Thus it will be seen that the plate a is only secured bythe spiral,

c. With this arrangement, the spring within the recess in the blind is unaffected by wather, and it is obvious it .may be made in a variety of forms. The lever is intended as the means of releasing the catch from the hook,

placed either on the outside of the building or on the windowsill. The catch is self-fastening.

I do no t claim the lever, except in its combination with the bar or plate havingthe catches. What I' do claim as my invention, and desi-re to secure by Letters Patent, is- The combination of the lever 7c, connected'with the stud 2, Aas described and employed, as and for the purposes set forth. Y

JOSEPH OURRIER.
